How to prolong the working life of traction motor of electric locomotive?
The traction motor is the power source of the electric locomotive, its effect on the electric locomotive is like the human heart, and it is a very important part of the electric locomotive.
However, electric locomotives need frequent driving, stopping, and emergency braking during work, so that the traction motor will be subject to frequent shocks and vibrations. In addition, although it is stipulated that overloading is not allowed, it is not uncommon for electric locomotives to be overloaded. Similar "convenience" illegal operations are more or less. Although these illegal operations seem to be nothing, they are actually depleting the life expectancy of the electric locomotive, especially the traction motor, which requires daily maintenance. And regular maintenance to ensure safety and prolong the service life of the traction motor.
If the sound of the traction motor is normal and there is no burnt smell during operation, then you only need to pay attention to the surface cleanliness of the traction motor and the tightness of the fasteners. If you are patient, you can also check the condition of the brushes.
During regular maintenance, the entire traction motor should be taken out and disassembled for inspection to see if there are severely worn parts and whether there is a short circuit. Among them, the commutator and brushes of the traction motor are the key inspection objects, whether their surfaces are smooth, whether the copper sheets of the commutator are filled with foreign matter such as carbon powder, etc. If there is any problem, it should be repaired or replaced, and if it cannot be solved, please contact the manufacturer.
The above are suggestions for prolonging the working life of traction motors.
